Hi everybody, just asking, as of title, if anybody knows how to create a taskbar button that opens a sort of popup showing some customizable directories...something like the launcher that kde4 has (if someone has seen it...)Edited_time_total

You might have to explain what you mean by "customisable" and "a popup".
I use a folder menu bound to button 2. Would it do the trick? You should be able to figure out the code.
(N.B. this is my second menu - the main one is bound to button 1, but I can't remember if that is a default in puppy these days).
